Based on the popular Israeli talent competition of the same name, the live talent show incorporates real-time voting by viewers through an app that is fully integrated into the show. Unlike American Idol and The Voice, which both start their seasons with taped auditions, Rising Star is live from the very beginning. Contestants audition with live performances, and viewers are able to vote for their favorite performers during every round during the performances. Those votes, along with the judges' feedback, determines whether the singer stays in the competition.

Paisley, Kesha, Groban and Ludacris will appear together for the first time during Sunday's Billboard Music Awards (8/7c, ABC).

Rising Star premieres on Sunday, June 22 at 9/8c on ABC. Will you watch?
